B. Follow Integer Rules for Addition and Subtraction
1) 63 ÷ 7 + 5 + 2² - 6 + 3= 15
Solution:
-Follow PEMDAS > Calculate
= 9 + 5 + 4 - 6 + 3
= 14 + 4 - 6 + 3
= 18 - 6 + 3
-Final Answer
= 15
2) 6 + (2 x 7 + 5²)= 45
Solution:
-Follow PEMDAS
= 6 + (2 x 7 + 25)
= 6 + 14 + 25
-Final Answer
= 45
3) 3(4 + 8²) - 8= 196
Solution:
-Follow PEMDAS
= 3(4 + 64) - 8
= 3 x 68 - 8
= 204 - 8
-Final Answer
= 196
4) 37 + 3 x 2 ÷ 6= 38
Solution:
-Follow PEMDAS > Calculate
= 37 + 6 ÷ 6
= 37 + 1
-Final Answer
= 38
5) 14 - 2 - 3 + 2 x 2= 13
Solution:
-Follow PEMDAS > Calculate
= 14 - 2 - 3 + 4
= 12 - 3 + 4
= 9 + 4
-Final Answer
= 13
